Protein data were analyzed using Perseus open source software. The numbers of significantly increased and decreased proteins for relevant comparisons were calculated (student’s t-test, p-value ≤ 0.05, false discovery rate (FDR) < 0.05). Diet based comparisons were SD/H-SD and SD/HFD. Differentially expressed proteins were further analyzed using Ingenuity Pathway Analysis (IPA)’s upstream analysis. Significant upstream regulatory molecules are described for SD vs HFD, and an activation z-score was calculated to predict activation of upstream regulators. A positive z-score indicates upregulation and a negative z-score indicates downregulation.
